Senile Anorexia

Definition

Physiological decrease or loss of appetite related to aging, characterized by reduced food intake without clear organic cause.

How it works

Senile anorexia results from multifactorial changes: slowed gastric motility, increased early satiety, modifications of taste and smell, decreased ghrelin (hunger hormone), and central regulatory changes of appetite. Unlike anorexia nervosa, senile anorexia does not involve voluntary restriction. Senile anorexia contributes significantly to malnutrition in the elderly and increases the risk of involuntary weight loss and fragility.

Role

Major factor of malnutrition and involuntary weight loss in the elderly.

Examples

• Rapid satiety sensation
• Low interest in food
• Skipped meals
• Progressive weight loss
• Reduced caloric intake

Recommendations

Offer frequent small meals instead of 3 large meals. Opt for nutritionally dense foods. Stimulate appetite with an appealing atmosphere and attractive presentation. Consider oral nutritional supplements.

Key takeaway

Managing senile anorexia through meal adjustments and appetite stimulation is essential to prevent malnutrition.
